Abstract

In a coaxial connector with a floating mechanism, a housing of a socket includes a housing base portion and a housing movable portion which can move radially over a plug-side end face of the housing base portion with a socket-side center contact. A top side of a plug-side shell is fitted onto the housing movable portion. A socket-side shell integrally includes shell contact plate portions which are exposed from the plug-side end face of the housing base portion. An end of the plug-side shell is configured to come into contact with the shell contact plate portions.

First claim

1 . A coaxial connector with a floating mechanism, including a plug and a socket to be connected to each other,
the plug including a plug-side center contact that is arranged at a center, a plug-side shell that is arranged outside the plug-side center contact, and a plug-side insulator that is interposed between the plug-side center contact and the plug-side shell, the socket including a socket-side center contact that is arranged at a center, a socket-side shell that is arranged outside the socket-side center contact, and a housing that holds the socket-side center contact and the socket-side shell in a mutually insulated state, the housing including a housing base portion that is fixed to a support member, and a housing movable portion that is radially movable over a plug-side end face of the housing base portion along with the socket-side center contact, a top side of the plug-side shell being fitted onto the housing movable portion, wherein the socket-side shell integrally includes a shell contact plate portion that is exposed from the plug-side end face of the housing base portion, and an end of the plug-side shell is configured to make contact with the shell contact plate portion, the housing includes a floating spring member that is fixed at one end to the housing base portion and at the other end to the housing movable portion; and the floating spring member includes a support fixed portion that is fixed to the housing base portion, a floating fixed portion that is fixed to the housing movable portion, and an elastically-deformable swing spring portion that connects the support fixed portion and the floating fixed portion, and the housing movable portion is movably supported by the housing base portion via the floating spring member.

2 . The coaxial connector with a floating mechanism according to claim 1 , wherein a contact plate escape groove is circumferentially formed in the housing movable portion, and the shell contact plate portion is configured to be able to escape into the contact plate escape groove.

3 . The coaxial connector with a floating mechanism according to claim 1 , wherein a sliding contact portion of arc-like chamfered shape is formed on an end of the plug-side shell.

4 . The coaxial connector with a floating mechanism according to claim 1 , wherein the plug-side shell includes a shell main body that holds the plug-side insulator, a movable shell of cylindrical shape that is axially movably held on a socket side of the shell main body, and a biasing spring that biases the movable shell to the socket side.

5 . The coaxial connector with a floating mechanism according to claim 1 , wherein: the socket-side center contact includes a contact portion that moves together with the housing movable portion, and a substrate connection terminal that is connected to a mounting substrate; the contact portion is integrally supported by the floating fixed portion of the floating spring member; the substrate connection terminal is integrally supported with the support fixed portion; and the socket-side center contact is integrated with the floating spring member.

6 . The coaxial connector with a floating mechanism according to claim 1 , wherein the socket-side shell includes a pair of elastic contact pieces that are opposed to each other at a distance in a direction crossing a direction from the support fixed portion to the floating fixed portion, the pair of elastic contact pieces being arranged outside the housing movable portions.

7 . The coaxial connector with a floating mechanism according to claim 1 , wherein a plurality of housing movable portions are movably supported by the housing base portion.

8 . A coaxial connector with a floating mechanism, including a plug and a socket to be connected to each other,
the plug including a plug-side center contact that is arranged at a center, a plug-side shell that is arranged outside the plug-side center contact, and a plug-side insulator that is interposed between the plug-side center contact and the plug-side shell, the socket including a socket-side center contact that is arranged at a center, a socket-side shell that is arranged outside the socket-side center contact, and a housing that holds the socket-side center contact and the socket-side shell in a mutually insulated state, the housing including a housing base portion that is fixed to a support member, and a housing movable portion that is radially movable over a plug-side end face of the housing base portion along with the socket-side center contact, a top side of the plug-side shell being fitted onto the housing movable portion, wherein the socket-side shell integrally includes a shell contact plate portion that is exposed from the plug-side end face of the housing base portion, and an end of the plug-side shell is configured to make contact with the shell contact plate portion, and a contact plate escape groove is circumferentially formed in the housing movable portion, and the shell contact plate portion is configured to be able to escape into the contact plate escape groove.

9 . A coaxial connector with a floating mechanism, including a plug and a socket to be connected to each other,
the plug including a plug-side center contact that is arranged at a center, a plug-side shell that is arranged outside the plug-side center contact, and a plug-side insulator that is interposed between the plug-side center contact and the plug-side shell, the socket including a socket-side center contact that is arranged at a center, a socket-side shell that is arranged outside the socket-side center contact, and a housing that holds the socket-side center contact and the socket-side shell in a mutually insulated state, the housing including a housing base portion that is fixed to a support member, and a housing movable portion that is radially movable over a plug-side end face of the housing base portion along with the socket-side center contact, a top side of the plug-side shell being fitted onto the housing movable portion, wherein the socket-side shell integrally includes a shell contact plate portion that is exposed from the plug-side end face of the housing base portion, and an end of the plug-side shell is configured to make contact with the shell contact plate portion, and a plurality of housing movable portions are movably supported by the housing base portion.
